This was only true for Vicky however up until about 3 days afterwards, when Vicky seemed to start to act very recklessly considering the humiliating consequences should Michelle decide that her behavior was bad enough to warrant another embarrassing family spanking. Scott pondered this and thought that her behavior was actually really really weird. Whenever he was around both Vicky and his mother, Vicky almost seemed to be goading Michelle into spanking her. Her face would be flushed and she would make nervous glances across at Scott to see his reaction as she pushed the boundaries further and further. Just once had his mother threatened to spank her when Vicky refused to do her homework, and the mention of it immediately sent Scott's blood pressure soaring, but disappointingly Vicky backed down at the last moment. The glances between the 2 of them were admittedly getting more and more, and Scott could feel a tension building between the 2 of them. Vicky, and spanking Vicky in particular started to play a more and more prominent part in his fantasies as he pleasured himself at night, replaying the spanking of a few weeks ago. Surprisingly considering her behavior, it was not Vicky that would be spanked next but his sister Chloe. They were all sitting in the kitchen having their breakfast, chatting normally and behaving well when Michelle stormed into the kitchen. "JUST WHAT DO WERE THESE DOING IN YOUR POCKET CHLOE!" she shouted as she entered the kitchen brandishing a packet of cigarettes. Chloe started to panic "erm ... I was just looking after them for a friend, there not mine!" she said trying to control the fear in her voice. "TELL ME THE TRUTH! NOW!" replied her mother. This was the moment that Chloe's fate hung on. She was terrified of what her mother would do. Every morning Matt and Katie from across the road would knock at their house so that they could all walk to school together, what would happen if they arrived and her mother was spanking her! The humiliation if news got out around her friends would be unbearable. She decided to continue with her story and insist that they were not hers. This was a big mistake. "RIGHT! THAT'S IT!, I was hoping that I was not going to have to do this again, but it appears that I was wrong!" With that, she then took one of the kitchen chairs and placed it in the middle of the kitchen facing the children. "Come here and take off your skirt" Chloe was mortified: "NO! NO! PLEASE! NOT NOW!, Matt and Katie will be here soon! you can't!" Her mother was un-moved by her daughters pleading "NOW!" Chloe was not giving up, but was painfully conscious that the longer she postponed the spanking the more chance there was that Matt and Katie would find out that she was still punished like a child. "PLEASE! do it tonight, make me strip again I don't care! just not now, PLEASE!" Scott was beside himself at the sudden turn of events and his cock was straining hard at his pants. "NOW!, or it's in the nude right now, just like last time" With tears of humiliation streaming down her bright red face Chloe went to her mother and removed her skirt. "And you knickers" Chloe knew this was coming, and with dread she pulled them down. "Completely off" said her mother. Trying to keep as much dignity as was possible she lowered her knickers and pulled them off, placing them on the kitchen floor. Scott knew he shouldn't look, but how could he not? His sister had perfectly shaped legs, with perfect silky skin. As she lowered her knickers she tried to avoid everyone seeing her pussy, but even so he got flashes of her soft pubic hair and the outline of her slit. "Hands on head" "OH GOD! NO! PLEASE!" "NOW! AND FACE THE TABLE, OR YOU STRIP" Chloe gave in, desperately worried that Matt and Katie would arrive before the spanking finished. Scott and Vicky stared at Chloe, having to put her hands on her head had pulled her school blouse right up giving them an unobstructed view of her entire navel and pussy. For the second time in his life Scott drank in the sight of her silky thighs and pussy, he felt like he would cum there and then. "Please! just get this over with", pleaded Chloe This was a mistake, and with her still standing her Mother smacked her naked bottom very hard "You" SPANK! "will" SPANK! "not hurry me!" SPANK! SPANK! SPANK! The fact that she was standing up meant that each smack pushed her hips forward luridly giving the children an even better view of her pussy. Michelle then told Chloe to bend over her knees, and began spanking her hard in front of the children. SPANK! SPANK! SPANK! SPANK! As before Chloe's intention of keeping her legs closed were short lived as the pain of the spanking increased, and her young pussy lips were exposed to all watching. As Scott watched the site of his sisters perfect legs and perfect pink bottom being spanked, the thing that Chloe had dreaded the most happened. They heard a knock at the door! Matt and Katie had arrived! Michelle paused in her spanking. "Vicky, will you get the door please" "NO! PLEASE!" Michelle ignored her and continued the spanking. "I" SPANK! "will stop" SPANK! "when I am ready" Shocked, and wanting to do everything Michelle asked to avoid a similar fate, Vicky went towards the door and opened it. SPANK! SPANK! SPANK! As Matt and Vicky entered the house they heard the final spank on Chloe's bottom. "What was that noise?" asked Matt. "Erm.. I don't know, Chloe must have dropped something" Matt gave her a funny look and asked whether the others were ready. Back in the kitchen, Chloe stood up off her mothers knee's and quickly put her knickers and skirt on before drying her eyes and walking out to see the other children. "You OK?" said Matt "Yeah fine .. just had trouble getting out of bed this morning" Scott's eyes locked with his sisters, and he felt she was pleading with him not to say anything. Vicky glanced at Scott, before noticing the bulge of his erection. Their eyes met again and she gave him a knowing smile. With that, they all started the walk to school, Chloe trying to limp as little as possible so that no one would know the throbbing that came from her well spanked bottom. Scott couldn't help re-running the events of the morning over and over all day long and had a great deal of trouble concentrating. Vicky's father was away on business, and when he got home his mother asked the children if they wanted to go to the cinema, but only Chloe said yes. At 8:00 his mother and Chloe left, leaving him and Vicky alone in the house. As was their normal routine they both had showers and got dressed in their pajamas before settling downstairs on the couch in front of the TV. Vicky had a pair of quite tight pajamas on that she had outgrown a while ago, and Scott couldn't help notice the fact that she wasn't wearing a bra. He couldn't help himself from keeping on glancing at the outline of her breasts, and the impression that her nipples made on the tight fabric. He knew that she was doing this was on purpose, and she seemed to be glancing across at him even more than usual to see if her attire caused any reaction. After about half an hour, Vicky brought up the subject that she had been desperate to talk about, but which up until now didn't have the nerve. Nervously, her heart pounding, she took a deep breath and started to talk to Scott. "erm, Scott, there's something I wanted to talk to you about, but it's really really embarrassing" Scott could guess what it was, and started to become aroused almost immediately "The other day, when .... when your mother sp .. spanked me" she stuttered "Yes" replied Scott in an equally nervous voice. "Well, did you enjoy seeing me being spanked?" Scott didn't know exactly where this was going. It was obvious that all of the spankings had had a huge affect on them, but he felt incredibly embarrassed about the whole thing. "Well, yeah, kind of I guess" Chloe took another deep breath "Well, the thing is, please don't ever ever tell anyone, but ..... I liked it too" "Your Kidding! .. why?" "I don't really know, at the time I wished the ground would open up and swallow me. I've never ever been so embarrassed in my entire life, but I can't help thinking about when your Mom made me pull my knickers down in front of you, and how you got to see her smack my bottom like a naughty little girl" "Oh" croaked Scott, his cock straining at his pajama bottoms once more. "I even tried to get her to do it again in front of you, but kept on losing my nerve at the last moment. Would you like to see me spanked again?" Scott looked at his nervous and flushed step sister, in his minds eye he saw the image of her plump buttocks as they bounced under the sharp smacks of his mother. He wasn't even sure what she was suggesting? Was she suggesting that when his mother and sister came home that somehow she would engineer another spanking? "Yes", was all he managed to croak. Trembling, Vicky then started to say the things that she'd been rehearsing in her mind all evening as she was hatching her plan "Well, I think I have been a very very naughty girl just having this conversation with you, and I wouldn't blame you if you decided that you should smack my bare bottom right now just for talking about it" Scott was beside himself. The nervous delivery and the way that she had chosen her words "naughty girl", and "smack my bare bottom" had obviously been to give herself as much of a thrill as possible. He couldn't stop himself if he wanted to. This game had to be played. "OK, stand up NOW!" he commanded Vicky, eyes downcast stood directly in front of him. "Pull your pajama bottoms down" he nervously told her. She slowly lowered her bottoms, leaving her in her top and white cotton knickers. "Take you knickers completely off and place them on the arm of the couch" He stared at her as she pulled her knickers off, before standing in front of him with her hands over her crotch. "Put your hands on your head, just like when Mom spanked you" Nervously, feeling very very exposed she put her hands on her head giving her step brother an unobstructed view of her pussy. Scott just stared for about 10 seconds. The last time this had happened he didn't want to be seen to be staring, but now he held no such reservations. Scott was still sitting down on the couch and Vicky's pussy was directly in front of him, only about a foot away. He felt like he had gone to heaven as he stared at her young slit, only partially covered by light blond wispy hairs. 'OK, now bend over' she bent over his knee, keeping her legs closed. He then rested his hand on one of her plump buttocks, allowing himself to caress it slightly as he felt the curve of her silky flesh. The contact drove him even wilder, and he heard Vicky let out a slight whimper as she parted her legs ever so slightly. SPANK! SPANK! SPANK! He rained down spank after spank, watching her buttocks bounce with each smack and quickly turn pink from the abuse. As he continued she opened her legs more and more giving him more and more of a view of her pussy. SPANK! SPANK! SPANK! SPANK! SPANK! Vicky was surprised by how much it hurt, but she was so incredibly aroused that she felt like she might have an orgasm at any moment SPANK! SPANK! SPANK! "OK, I'm really really sorry I was naughty, please stop spanking me, I'll do anything you want if you do" "OK, stand up and take off you pajama top" Vicky, trembling did as she was told, faced her step brother and removed her top exposing her breasts for the first time. No boy had ever seen her naked before, and like most teenage girls she was insecure about her body. She felt so incredibly naked as she stood before her fully clothed step brother. She didn't know where to put her hands, so crossed them in front of her breasts hiding as much as she could. "Hands on your head, just like when Chloe was spanked the 1st time" said Scott She complied, and stood there allowing Scott to ogle her entire naked form. She was slightly on the plump side, although because she was still in the 1st flush of youth this was not at all unattractive. Her skin was very pale, and flushed with a mixture of sexual excitement and embarrassment of being so exposed. Her breasts were about a b cup, perfectly shaped small white mounds with light pink nipples and large aureole. Scott desperately wanted some sort of release, he couldn't believe that he was sat down fully clothed with a completely naked girl in front of him. He reached out and gently stroked her soft belly, before moving up to cup a delightfully soft breast in the palm of his hand. Vicky just looked straight ahead as she allowed Scott to explore her body as she just stood there. His hands went lower down to stroke the tops of her thighs, which Vicky parted with a soft moan, desperate for him to touch her sex. He then told her to go upstairs into her bedroom. Confused, she started to put her knickers back on, but he stopped her and told her to go there naked. She picked up her clothes and started to walk to her room with Scott behind her. Walking through the house, completely naked made her feel even more exposed and on display. Once they got to her bedroom she wasn't sure what to do, so just sat down naked on the end of the bed. Scott walked over and sat down beside her. Vicky wished that Scott wasn't still fully clothed as it added to the weirdness of the situation as she tried to pull in her belly and thrust her chest out to make her breasts look bigger in front of him. Scott pulled her face towards his and while looking into her eyes cupped one of her small breasts in the palm of his hands. They were both very inexperienced and when Scott went to kiss her it was clumsy as was her response. Both of their tongues were soon intertwined however as Scott kneaded her young breasts passionately. He then told her that he intended to take her up on her offer of doing anything he wanted if he stopped spanking her, and that she was to lie down on the bed. She did so, and he gazed at her naked form. "Open your legs as wide as you can" Nervously she did as she was told, completely exposing her moist pussy to his greedy eyes. He then took his finger and rubbed it gently on her clit, leading to an immediate response. It didn't take long for him to masturbate her to orgasm, and she bucked wildly as she explosively came under his inexperienced hands. He then dropped his pajama bottoms and underpants letting his engorged cock spring free in front of a girl for the first time, and asked her if she would return the favor He laid down on the bed and Vicky took hold of his cock and rubbed it gently up and down. As inexperienced as Scott, she was also very clumsy, but in his state of extreme arousal with a naked teenage touching his cock he came in under a minute. Exhausted, they lay together touching one another's naked bodies and talking about the games they would play over the next few weeks. It was going to be a fun time
